  is it in the active site? does t mean that if sometinh affect this group, the enzyme won’t be able to do its job?

  -SH groups come from Cystein in the protein. They can probably be involved in some active sites, but this is not a rule. However disulfide between 2 cysteines are often important for protein structural stability

  In a protein, an AA with SH in the end of lateral chain (if I ‘m not wrong is metionine) can make S-S bonds.
